Application February 21, 1934, Serial No. 712,392

4 Claims. 221-62) The invention relates to dispensers for tooth powder and has for one of its objects the provision of means whereby the tooth powder is kept in a sanitary condition and is at all times rea for application to a toothbrush.

A further object of the invention is the provision of a tooth powder dispenser comprising a container to retain the tooth powder having a series of openings in its bottom through which the powder will be dispensed, and means actuated by a toothbrush to expose the openings and spread the powder on the brush, said means being provided with a closure for the openings that is normally held in position by spring means to prevent dispensing the powder.

A further object of the invention is the provision of means actuated by the tooth brush to agitate the powder in the container so that it will be free to pour through the openings for distribution on the brush.

The invention will be described in detail hereinafter and will be found illustrated in the accompanying drawing, in which Figure 1 is a side view in elevation of my improved tooth powder dispenser,

Figure 2 is a front view in elevation,

Figure 3 is a fragmentary rear view,

Figure 4 is a vertical sectional view on a plane indicated by the line 44 of Figure 2,

Figure 5 is a fragmentary sectional view on a plane indicated by the line 5-5 of Figure 1, and

Figure 6 is a horizontal sectional view on a plane indicated by the line 6-6 of Figure 1.

In the drawing similar reference characters are used to designate corresponding parts in all the views.

The tooth powder dispenser includes a container 10 for holding the powder that comprises two removable sections 11 and 12 so that powder may be replenished in the container by disconnecting the two parts and the parts 11 and 12 may be held together by friction or by any other suitable means.

The part 12 when the dispenser is in operative position forms the lower part of the container, and the bottom wall thereof designated 13 is provided with a series of openings 14. Slidably mounted on the bottom wall 13 by means of angular supports 15 is a toothbrush receptacle 16 having its front end provided with an opening 1'7 to receive the toothbrush designated A. The top wall of the receptacle 16 is provided with a series of openings 18 that aline with the,openings 14 topermit the tooth powder to pour from the container 10 on the brush bristles. 19 designates an.

expansible coil spring engaging the rear wall of the receptacle 16 and normally holding the openings 18 out of alinement with the openings 14. Spring 19 terminally engages a supporting plate 20 secured as shown at 21 to the portion 12 of the container and supports the container by engaging grooved guides 22 on a plate 23 that is adapted to be secured by means of driven fastenings 24 to an upright'support (not shown).

Secured to the upper wall of the receptacle 16 is an upwardly and rearwardly inclined arm 25 that extends through one of the openings 14 in the bottom wall 13, and connecting the arm 25 and theopposite wall of the portion 12 is a contractile coil spring 26, said coil spring being designed to agitate the tooth powder in the receptacle to prevent it from clogging and to insure ready pouring thereof through the openings 14 and 18 when alined as heretofore described. As shown in Figure 5 the spring 26 is kidney-shaped in cross section with cusps 27 extending upwardly, this shape of spring having been found best to answer the purpose of an agitator.

In using the device the container 10 is filled with the powder when the device is removed from the holding plate 23 and turned bottom upward, and after being filled and the part 12 placed in position, the device may be supported on the plate 23 in the position shown in the drawing. To supply a toothbrush with powder from the container, the brush will be inserted in the receptacle 16 and by reciprocating the receptacle 16 by pushing on the brush to move the receptacle against the resistance of the spring 19 and thenpermitting the spring 19 to react to return the receptacle to its original position, the openings 18 will expose the openings 14 in the rearward movement of the brush against the resistance of the spring to permit the powder to pour onto the brush, and when pressure on the brush is removed the spring reacts to keep the openings closed, the arm 25 operating as a stop to limit the movement of the receptacle under the impulse of the spring 19.

What is claimed is:-

1. A tooth powder dispenser, comprising a powder container, the bottom of the container provided with an opening, a plate slidably mounted on the bottom and having an opening adapted to register with the first mentioned opening, an arm secured to the plate and extending through the first opening, and a contractile coil spring connecting said arm and a wall of the container to agitate powder in the container.
